Yamaha LF350ESA Outboard Motor

35-Inch Shaft | 4.3-Liter V6 | Digital Electronic Control | Electronic Fuel Injection | Electric Start | Power Trim and Tilt | Gray | Counter Rotation

The Yamaha LF350ESA is the 35-inch counter-rotation version of Yamaha’s 4.3-liter V6 offshore outboard. It’s built for larger offshore boats with deeper transoms, where pairing a counter-rotation unit with a standard-rotation engine helps the boat run straighter and eases steering torque. The V6 design delivers strong horsepower and torque while keeping weight and fuel consumption in check, especially compared to the older V8 platforms. With Yamaha’s DEC system, throttle transitions are smooth, shifts are clean, and the motor stays predictable even when conditions get choppy.

⚠️ Important: This Digital Electronic Control engine must be installed by an authorized Yamaha dealer. The outboard and DEC system require flashing and configuration using Yamaha diagnostic tools. DIY installation is not supported.
